A CT scan of the knee can be done with either a 16-row CT or a 64-row CT. The price for a 16-row CT is about$263.20 and a 64-row CT is about$366.60. CT of the knee mainly looks at the bone quality of the bones of the knee joint to see if there are obvious fractures, osteophytes, free bone in the joint, and fluid in the joint cavity. However, CT examination of the knee joint is not able to see clearly the condition of the ligaments and meniscus of the knee joint. If you want to clarify the extent of damage to the ligaments and meniscus of the knee joint, you must have an MRI, which is the first choice. MRI can clearly show the extent of damage to the ligaments and meniscus of the knee, which can help the clinician to formulate the next step of treatment.
